Abstract

Paper-fibres are studied for use as a pore-former to produce gas channels in the anode substrates of solid oxide fuel cells (SOFCs). These fibres produce cylindrical pores within the anode substrate, which are different from the pores formed by the conventional pore-formers such as wheat flour and graphite. The cylindrical pores make it easier to connect each other to form continuous pathways for rapid gas diffusion. Paper-fibres can create more open porosity than the same amount of flour. The application of the paper-fibres significantly improves the cell performance by enhancing the gas diffusion process. The anode-supported YSZ film cells with 5 wt.-% and 10 wt.-% paper-fibres exhibit maximum power densities of 0.72 and 1.06 W cm^-2, respectively, using hydrogen as fuel and ambient air as oxidant at 800°C.
